A small company manufactures a certain product. The price-production relationship for this product is P = -0.7*D + 300, where P is the unit sales price of the product, and D is the annual production (number of units produced). Suppose variable costs are $23 per unit produced and fixed costs are $11,317. Find the break-even point (minimum number of units that must be produced for a business to become profitable). Note: there are 2 roots in the breakeven equation, choose the smallest root. Margin of error: +/-2 (answers within range [x-2, x+2], where x is the true answer, are considered correct).
